Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a track branching device including a plurality of movable track girders in order to moderate the angle of incidence in a branching device such as an new transportation system.

This type of branching device has more relative moving parts than the conventional branching device with one movable track girder, so the structure is complicated and the weight increases, which not only increases equipment and maintenance costs but also reduces safety. There were also problems, and improvement of these shortcomings was desired.

The present invention was made against this background, and the hinge part of each movable track girder divided into a plurality of parts is connected to the input side fixed track girder for the first movable track girder, and the first movable track girder for the second movable track girder. At the moving end of the movable track girder, the movable track girder one movable track girder is provided with a center pin support at the movable end, and the movable track girder's movable end is provided with a sliding plate support or roller bearing on the ground side. Alternatively, in the present invention, at least one center pin insertion hole is formed as a long hole in the direction of the track axis, and the moving side end of the movable track girder is guided so as to be guided at right angles to the track axis direction. The feature is that it corresponds to the change in length in the track direction when the movable track girder turns, and the structure is simple and light in terms of the fixed track girder, movable track girder, and pivoting with the ground side. The object of this invention is to provide an inexpensive branching device that is excellent in terms of safety.

Below is a single opening 2 of a 3-wire track with a running guide rail in the center
An embodiment of a horizontal rotation type branching device for a joint pin joint will be described based on the drawings.

Figures 1 and 2 are plan views of the point in normal and reverse positions, respectively, and Figures 3 and 4 are views of the point in normal position with the central pin insertion hole as an elongated hole. 5 is a side view of FIG. 1, and FIGS. 6, 7, and 8 are cross-sectional views of VI-VI, ■-■, and ■-■ of FIG. Show your husband.

The movable part disposed between the entrance side fixed orbit girder 1 and the branch side fixed orbit girder 2 is divided into two, and the first movable orbit girder 3 and the second movable orbit girder 4 are successively stepped up.

Then, a center pin 7 is erected at the end 6 of the entrance side fixed orbit girder 1 fixed to the basic structure 5 provided on the ground side.
An insertion hole 9 formed in the rotation center side end 8 of the first movable track girder 30 is loosely fitted into the first movable track girder 30, and the first movable track girder 3 is supported so as to horizontally rotate about the center pin 7.

The vertical load on the end 8 on the rotation center side of the first movable track girder 30 is applied to the sliding plate 10 provided at the end 6 of the input fixed track girder 1 and on the rotation center side of the first movable track girder 30, as shown in FIG. It is supported by a sliding plate 11 provided at the end portion 8.

As shown in FIG. 7, the vertical load on the movable end 12 of the first movable track girder 3 fixes the sliding plate 13 provided at the end 12 onto the base plate 14 provided on the ground side. It is slidably supported by a sliding plate 15.

Center pin 1 erected on the moving end portion 12 of the first movable track girder 3
6, the insertion hole 18 formed in the rotation center side end 17 of the second movable track girder 40 is loosely fitted into the second movable track girder 4, and the second movable track girder 4 is inserted into the center pin 16.
It is supported so that it can rotate horizontally around the center.

As shown in FIG. 7, the vertical load on the end 17 of the second movable track girder 40 on the rotation center side is
It is supported at the movable end 12 of the movable track girder 3 via a sliding plate 20 provided at the movable end 12 .

Both flanged rollers 22 are pivotally supported at the lower part of the movable end 21 of the second movable track girder 4, and the rollers 22 are engaged with guide rails 24 laid on a basic structure 23 provided on the ground side. death,
The movable side end 21 of the second movable track girder 4 is horizontally rotatable so as to be guided at right angles to the track axis direction, and as shown in FIG. The vertical load on the moving end is supported by the rollers.

Further, the insertion hole 18 formed in the second movable track girder 4 is formed as a long hole in the direction of the track axis.

This is because the guide rail 24 is formed into an arc of R centered on the center pin 7 of the fixed track girder 1 on the entrance side as shown in FIG. Since the track axis length of the girder 4 is bent between the first and second movable track girders 3 and 4, t when the girder is in the upright position in Fig. 1 is shorter than t2 when it is in the reverse position in Fig. 2. I have to throw it.

For this purpose, the insertion hole 18 of the second movable track girder 4 is formed into a long hole in the track axis direction. The insertion hole 18 is configured to be movable on the track axis, and the distance between the movable end 21 of the second movable track girder 4 and the end 25 of the branch-side fixed track girder 2 is constant.

This elongated hole can effectively cope with out-of-synchronization of the movement of each movable track girder at the intermediate point of the switch.

In the above embodiment, the movable track girder is divided into two parts, but the present invention is not limited to this. The insertion hole may be a long hole in the axial direction, or a track girder other than the second movable track girder may be used. As for the support means, a sliding plate or a roller bearing can be selected as necessary, and in order to horizontally guide the moving side end of the movable track girder perpendicular to the track axis direction, a sliding plate can be used instead of a combination of rollers and guide rails. This may be done by engaging the concave and convex portions with each other.

Since the present invention is configured as described above, each movable track girder of the branching device in which the movable track girder is divided into a plurality of parts and the angle of incidence is relaxed can be easily and firmly supported, and furthermore, it can be safely supported. This has great effects, such as being able to cope with synchronization deviations in the movement of each movable track girder.
